Bulgarism is an ideology aimed at the "revival of Bulgars' national identity" and Volga Bulgaria statehood.
[2] It originated in the second half of 19th century within the Wäisi movement[3] and the Society for the study of the native land (Chuvashia).
[4] It was revived at the end of the 20th century as "neobulgarism" in Tatarstan, Bashkortoston and Chuvashia.
The theory was supported by the Soviet authorities in mid-20th century as an alternative to the "reactionary" theory claiming the Golden Horde descent.
[5][6][7][8] In the 21st century, the ideas of Bulgarism have been revived through the activities of Neo-Bulgarists.
